Objective: It is supposed that Transcranial Doppler ultrasonography (TCD) during thrombolysis may help to expose thrombi to tissue plasminogen acPvator (t-PA). The aim of this study is to determine if TCD can safely enhance the thrombolyPc acPvity of t-PA.
Material and Methods: Patients with acute ischemic stroke which fufill current criteria to intravenous t-PA treatment were randomly assigned to receive continuous 2 MHz TCD (the target group) or placebo (the control group). In follow up analysis, outcomes are defined as good (as indicated by a score of 0 to 2 on the modified Rankin scale) or favorable (scores of 0 to 1 on modified Rankin Scale).
